Abstract (en)

A fuel cell, comprises a fuel cell element (16) comprising a solid electrolyte layer (10) of oxygen ion conduction type which is interposed between a cathode layer (12) and an anode layer (14). The cathode layer (12) and the anode layer (14) are exposed to a mixed gas of a fuel gas, such as methane or others, and oxygen, to cause an oxidation-reduction reaction between the fuel gas and the oxygen, by means of the cell element (16), to generate an electromotive force. The anode layer (14) is mainly composed of a metal which is oxidation-resistant against the mixed fuel at the operating temperature of the fuel cell element (16), or a ceramic having an electroconductivity. The anode layer (14) is further blended with a metal or an oxide thereof, selected from rhodium, platinum, ruthenium, palladium, and iridium. <IMAGE>
